HAT-FORMING DIE Applicationiled May 22, 1926. Serial No. 111,017.

This inventionl relates to hat making or forming dies and moreparticularly to a novel and improved method of shaping the material toproduce what may be termed a` full 5 crown or flat crown turban hat.

The primary object ot the invention rer-- sides in the construction of ahat shaping and forming die designed to steam theamaterial during theVforming or shaping p-roc` 10 ess, @including provision or'makingvarious sized and shaped hats with rapidity and skill and with a minimumamount of hand labor.

One of the objectsof myzinve'ntion is to provide ia steam? chamber orformingdie 15 into which the Vmaterial to .be pressed Vor shaped nmaybeheld, the same being soA arranged that the material to be pressed orshaped will be held therein in proper position andthe die will be soformed that it is 29 readily adapted to receive the shaping member. .f

Trouble has been experienced inl applying to the interior of the die-a.`forming member' between the walls of the die'and itself, theV materialIto be shaped,l which, at the same time `may be steamed-dueto theconstruction V of the die. n

A further Particular object of the inventionl is to construct the dieand itsparts so that-either a full crownturban may be formed or aflat-crownturban, the arrangement ot the dies'being provided so that thegoods may be interiorly` worked or eXteriorly worked dependingupon' theshape of ,the hat desired.

VMy improved construction is especially adapted for :tormingvoutot1 thestock mate- V rial, yelour, eltVbeaver or buckram or the like,` ahat,-the` forming `member and dies being so arranged that they vcan bereadily disassemble'dtor..cleaning and will have fewnumberofvparts.whereby they can be quickly assembledor replaced `toprovide various forms of dies, depending upon the shape of hat, theconstruction of which is contem-` plated. Y

To enable others skilled in the art to fully comprehend the underlyingfeatures of my invention that theymay embody the same in the 'variousmodifications rin structure `con- "Y templated, drawings depicting apreferred form'havebeen annexed as a part ot' this' disclosure and insuch drawings, similar'reterence characters denote corresponding partethroughoutV all the views, of which, j

Figure l is a view of the upper or working portion of a die machine inwhich is formed or blocked the material making up hats and showing thehat material in place within the die readyto be formed by a sack formingmember which I employ.

Y Iigure 2 is an enlarged Y cross section through thedie and the sackholding membernand illustrating the construction of both.

Y`Iifgure` 3 is ai crosssection taken through a hat constructed in thedie shown in Figure 2, and providing the full crown eiect as desired.l Yl Figure 4 is a modified form ot sack or pouch such as shown in Figure lbut having formed therein an enlarged body portion. y

Referring to the drawings in detail, 5 indica-tes the die holding trameof an operating machine, such for instance, as thef ma` chine shown inmy Patent Number 1,530,001 granted March 17, 1925. The cross head 6thereof is a'djustably carried by the screw members 7 which are operatedin any suitablemanner to raise and lower the die carrying ltrame 8 whichconsists of a plurality ofpost members, holding at their lower ends, thesack carrying plate 9. This plate is provided with a boss l0 in which isthreaded an air hose connection ll through the medium of which air maybe supplied to the interior of a rubber or other yieidable sack 12,where by the same when placed within a hat forming guide, may beinl'lated and depending upon the air'pressure Supplied through theconnection ll will press the hat material between the sack and the innerwalls ot the die.

In the invention shown vin Figures l, 2 and 3 and l, I have illustratedone method of IUD working a hat, the hat being of the turban type andbeing interiorly worked to provide therein the shape desired. ln orderto hold the sack 12 in position on the carrying plate 9, 1 provide aclamping ring 13 which is secured to the plate 9 through the medium ofthe screws 19C, shown in Figure 2. The sack is susnended from the plate9 and is in position directly over the die and being carried upon vthethreaded members 7, can be lowered into the die at will to besubsequently inated to shape the hat material. In Figure 1, l have shownin position in the die member, cone-shaped material made of velour,felt, beaver, buckram or the like material suitable for the manufactureof hats as .supplied or ready cut in the trade.

It will be noted that this cone-shaped piece of material 15 is disposedwithin a hollow die which is in the nature of a pot, the lower portionof which is bowled, it being of course understood that any shape et diemember may be used, depending upon the shape to be given the hat whichis to be blocked. rlhis dic member is suitably secured' to the top plate1G of a steam chamber 17 'through the medium of the screws 18, the upperwall of the die being thickened as at 19 and having its innercircumference shaped as at 20 to accommodate a holding or wedging ring21. The die 19 is provided, as is the plate 16, with perforations oropenings 22 through which the steam may pass to affect the material tobe blocked in the usual manner. The steam pot 17 is smaller` at its basethan in its upper portion and through the medium of the lugs 23 andthumb screws 24, the same is suitably secured to the bed 25 of themachine hereinbefore referred to. The steam pot has the usual steaminlet 26 and outlet l27 through which the same upon manipulation of thevalve 28 can be supplied with steam to affect the material to beblocked.

Referring to Figure 2 particularly, it will be noted that when thematerial 15, which, as before mentioned is sold in the trade insubstantially conical shapes, has been placed,

as shown in TFigure 1 into the die 19, the holding or clamping ring 21is placed inside the hat material 15 and fastens the same to the upperedge of the die, the holding rings securing the same in position in thedie through the meeium of its frictional contact with the curved wall 2Oof the upper, inner periphery of the die as hereinbefore eirplained.lWhen this ring 21 has been positioned, the upper edge or protrudingportion of the hat material is turned in over the ring at 29 and theupper frame or head 6 of the machine is lowered until the sack 12, asshown in outline in Figure 2 is resting in position upon the material inthe bottom of the die. lt will be readily seen from Figure 2 that whenthe-sack is inflated under pressure, the same will take substantiallythe contour of the die or the material as turned in and will effectivelyblock the same to the shape of the die, it being of course under'- stoodthat various shapes of hats may be provided by changing the innercontour of the die. i

When the hat has been blocked to the shape desired, the inner fold 29 isdrawn out and the ring 21 removed, after which the extended portion 29of the material is cut oli' or the inturned portion of the material istrin'nned as desired and as shown in Figure 3, a hat of the full turbandesign is produced.

lt is to be understood that any shape of sack may be used or that thesack may be made of any suitable materialv such, for instance, asrubber, rubberized cloth or any air-proof or steam-proof material, also,any of the parts of the device, such for instance, as the blocking coreorshaping ring may be made of metal or rubber as desired and thatanyshape of die may be used, depending upon the style of hat desired.

It is evident, therefore, that l have provided an etlicient means forinteriorly and exteriorly blocking or Working hats. In this particularinstance, I may designate the hat as of the turban style but it is to bedistinctly understood that a hat of any style can be formed through theuse of my blocking element.

The process of blocking the hat, as shown in Figure 1, would comprisethe placing of the material into the die and then placing the ring intosaid material so that the same was wedged in position in the die. `Thematerial is then folded in and the sack lowered thereinto so that itwill shape the crown and produce the proper head size. After theblocking' has been completed, the material is removed, allowing theholding ring 21 to fall into the pot or die after which the material istrimmed as desired.

It will be seen therefore, that I have provided an improved method ofshaping and blocking a hat which could be varied to suit the shapedesired and also wherein modiications as to size and form may be readilyaccomplished.

'lNhile I have illustrated and described my invention with some degreeof particularity, realizethat in practice various alterations thereinmay be made. I therefore reserve the right and privilege of changing theform of the details of construction or otherwise altering thearrangement of the correlated parts with out departing from the spiritof the invention or the scope of the appended claim.

Having thus described my invention, what I claim as new and desire tosecure by United States Letters Patent is A hat shaping devicecomprising a steam pot, a closure forv the top of the pot, a perforateddie suspended from said closure, and

having an outwardly ared upper edge and adapted to receive the materialto be shaped, a wedging ring tapered in cross-section insertible intothe upper flared edge of the die Jfor holding the material in placeagainst said flared edge and over which `the excess material can beturned into the die, said ring vmaintaining its position within the dieby frictional Contact of one of its tapered sides with the flared upperedge of the die, a sack carry ing'plate having a pressure inlet, aninflatable sack carried by the plate, means for moving the plate toposition the sack exteriorly or interiorly of the die, a clamping ringfor retaining the sack in position on the plate and said Clamping ringbeing arranged t0 engage the wedgin g ring whereby the hat Inaterialwill be held securely in position during a shaping operation.

In testimony whereof I affix my signature.
